16 channels High Speed 5W Radio Modem FC-302 with RS-232 for Data Collection
Abstract
FC-302 is a synthesized 5-watt FM UHF/VHF Wireless Radio Modem, which is designed for data transportation and voice communication. For the voice communication, it can support selected pre-emphasis, squelch and audio amplifier. The radio is PLL(Phase Lock Loop Synthesizer) /microprocessor controlled with optional FSK, GMSK, 4FSK modem, and 16 channels. The application of two-point modulation with good low-frequency response in the radio also makes it a competitive choice for 1200-19200bps rate data application. Compact dimension and wide range DC support make it flexible to use. CE FCC certified.
